Fix composite Crossgen2 runs on Windows and clean up R2R pipelines (#43261)

Some time ago I introduced a new option "crossgenframeworkonly"
in the test build scripts and I modified the CoreCLR pipeline
to use it. Turns out it was never fully functional, crossgenning
framework continued taking place in the CORE_ROOT population phase
(generatelayoutonly) and only on Windows it got duplicated in the
subsequent "crossgen framework" step. This duplication moreover
uncovered a bug in the R2RTest tool - when compiling the framework
in composite mode twice in a row, the tool was incorrectly
manipulating the composite file "framework-r2r.dll", causing an
error in the second framework crossgenning step.

I believe that it's completely logical to crossgen the framework
as part of populating CORE_ROOT. In light of this fact I have just
deleted the separate "crossgen framework" step and the corresponding
build script options. I have also fixed the described bug in R2RTest
related to repeated framework crossgenning in composite mode to
restore the invariant that framework crossgenning should be idempotent.

Thanks

Tomas
